After more than six seasons of budgeted, on-the-clock renovations on Restaurant: Impossible, Robert Irvine has seen seemingly everything — the good, the bad and the ugly — in eateries across the country. From unpalatable food and unsafe cooking conditions to creepy-crawlies covering the furniture and floor, the scenes at some of these restaurants are simply shocking, to Robert’s Restaurant: Impossible team and at-home viewers alike. No matter how dirty or downright disheartening a situation may be, however, Robert has never walked away from a challenge, successfully transforming nearly 70 eateries to date.

Over the years, Robert has proved his trademark to be his ability to breathe new life into once-failing establishments and give them the second chance they deserve. In the form of revamped menus and updated designs, plus tried-and-true techniques for food buying, handling front-of-house management and overseeing day-to-day operations, he outfits businesses with everything they need to not just survive but thrive. And ultimately his commitment has led to awe-inspiring transformations, especially given that his updates must be started and completed in just two days and can cost no more than $10,000.
